There are two ways that a person can close their browser after watching this, either understanding everything, leaving a like, and stating how much the video helped in the comments, or you can leave more confused than ever and fail your math exam that's in 2 days. I'm in the first type, thanks Sal.
For the past week I haven’t understood a single thing in math. I have a test tomorrow and I was freaking out because I didn’t know how to do ANYTHING. this video helped me a lot!!!
4:44 *TO PEOPLE WHO DONT UNDERSTAND:* Basically, he's saying shade the bottom half of the boundary line because all of the solutions are less than () 4x+3 (y=4x+3) you would shade the top half
Or use vise versa : it depends on technique used to select the target region. For example here is an opposite technique ua-cam.com/video/-fYv_ER9NA8/v-deo.html
good morning fellow reader! is ur lucky day, im gonna tell you a legit shortcut on what to shade after you graphed the linear iniquality if y is on the right ex: y
thats a bad method because if you just copy this, it shows that you dont actually understand whats being done here and why you should be shading something. The best way to get good grades is by actually understanding the subject.
Khan you are AMAZING! Every time I want to learn something about math, all I have to do is search x plus khan (where x is the thing I want to learn) and BOOOM! Twelve or so minutes later I know it.
What's interesting is that I'm a math teacher and I thought that this explanation was perfectly clear, but I'm reading the comments, and it looks like the commenters who are students are still confused. I will definitely break this down a little differently when teaching it.
hello for everyone who didn't understand im going to explain it here clearly y = mx + n it refers to the position we start on the graph if we have n to 3 we start from 3 on the y vertical line now if m is 2 from the point we started we go 2 points up so we will be on the y =5 and one verticaly so x = 1 then y 7 and x 2 , y 9 then x 3 if m was -2 we would start at 3 and go down 2 verticaly and 1 horizontali y 3 x 0 then x 1 y 1 then x -1 y 2 ... now if x was 1 over 3 x that is a fraction and we start y 3 x 0 we would go y 4 x 3 then y 5 x 6 and so on for minus we would go down i hope this helps
sir ,good explaination,but in short we can directly substitute (0,0) to find feasible region of inequation instead of substituiting all the values i.e -1,1.if inequation gets satisfaction by origin ,its feasible solution will be on side of origin or else another side .
we go in the one direction because youre supposed to graph the point. After you graph a couple of points, you graph or connect them to make a line. Why are you supposed to graph a line? Because this is math class.
I just wanted to say thanks for this bc it did help me understand the concept in a way, ik the creator might not see this but if you doooo then thanks honestly I would have failed school if these videos were never made lol
I think I have it now! I was plotting correctly and using the dash and solid lines. But when it came to coloring it in on the computer it would not work. I think I was coloring the line too or not going above what was included. Still a little tricky.
y> dotted line/shade up
y>- solid line/shade up
y< dotted line/shade down
y
Thanks for this, this helped a lot (:
Kaitleen Tolentino No problem ;)
SoluriZe thanks
SoluriZe is this 100% true? Or sometimes not
it only applies for when it is in slope intercept form, if it is in standard form for example you have to use a test point
Speaker:"This is the hardest part"
Me: Isn't everything hard? What?
lol manual labour is hard
EXACTLY
Definitely the type of video you watch after actually going to class.
How'd you know
I'm watching in class.
I just woke up from
Dude same
this video is 12 years old. And it is still helping many people to improve their understanding of inequalities and their graphs. Brilliant work, Sal !

I'm in the first type, thanks Sal.
i’m the second type bro i am not passing any math tests 💔
@@urfav_julezz good luck fam, check organic chemistry tutor, he's good too
I love how it takes a teacher 45 minutes to an hour to teach what you taught in eight minutes
My teacher is making us watch this in online classes lol
because he's from MIT
i love how people say "i love how" even though they dont love it.
@@Sohlstyce I love how you said I love how people say I love how when they don’t actually love it
For the past week I haven’t understood a single thing in math. I have a test tomorrow and I was freaking out because I didn’t know how to do ANYTHING. this video helped me a lot!!!
This guy has helped me through so many math classes, it's unreal
yeah didnt understand a single thing
S. M .T same
Lmao
S.M.T THE BEST COMMENT
Thats easy.. How can u not understand that
Same
your straight line standards are high!
I’m sorry am the only one trying to learn how perfect this guy writes with a mouse?
in his book he said he bought a drawing pad before starting the academy
It's a graphic pad boy
@@shivrammohan9081 Nah, it's a painting pad.
its probably a drawing tablet
IKR
This is so much simpler than the graphing inequalities my teacher was doing, not sure how anyone else can have an issue, its pretty straight forward

i love this guy
Everything is so much clearer now! Thanks, Sal!
Great one!
OMG Thx Im reviewing for a semester exam and I forgot how to do this
Helped a great deal, thanks!!
YOUR WELCOME
good morning fellow reader! is ur lucky day, im gonna tell you a legit shortcut on what to shade after you graphed the linear iniquality
if y is on the right ex: y
Harrykyle99 THANK YOU SO MUCH

glad to help
Thanks bro it was more helpful than the video

you just confused me even more...
leslie ramirez same 😂😂😂😂
same
me too
you confused yourself he just turns everything into bare bone using logic tbh u are hopeless if u dont get this
😂😂
Thank you, you made math fun
Everything is Fun. it is just a matter of precedence.
A week in my class and I didn't understand a thing. This saved me. Thanks guys!
YOUR WELCOME
Thanks sooo much!! This helps loads, I finally can understand what i am doing!!
it really does help.
NO IT DOESNT
Thanks Sal! i never kind of lost my attention during the class.
I LOSE IT ALL THE TIME
11 year old videos are still useful
Thanks this really helped.
Khan you are AMAZING! Every time I want to learn something about math, all I have to do is search x plus khan (where x is the thing I want to learn) and BOOOM! Twelve or so minutes later I know it.
It helped a lot
Can u do one on how are Equation and inequalilty alike
Hi! I didn't watch but you may try my explanation, it might work for you! ua-cam.com/video/-fYv_ER9NA8/v-deo.html
what if there was a number before the Y?
such as 2x+4y>7
Omnia Ali you divide every number by the y value
u rearrange to formula to the general form y=mx+c
yes u are correct my boi.
Make y the subject
really helpful you make it seem so easy
I KNOW RIGHT
People who say he’s confusing you need to realize the only reason you’re confused is because you’re missing necessary understandings of math.
Or there reading the comments and not focusing
Thanks Khan 👍
nice...... understood
Love you khan academy!!!!!
Yeah thanks. More confusing than ever.
This was very helpful
ty ur videos really save me alot.
Very helpful thanks alot
understood everything, thanks Khan
RESPECT HIM G, HIS NAME IS SAL

The video seems a little bit confusing at times but I'm pretty sure I got it thank you!!!!
YESSIR
This is helpful! Thanks!
ONG
THANKS I GOT AN A+ ON MY TEST
THANK YOU THANK YOU THANK YOU!!
"And hopefully it will look dashed to you". HAHAHAHA LMAO
awesome thank you!!!!
Thankyou 😇
Thank you Mr khan 😩
This was extremely confusing🙁
Hi! I didn't watch but you may try my explanation, it might work for you! ua-cam.com/video/-fYv_ER9NA8/v-deo.html
Thanks! This was helpful
ok this just made things even more confusing
Thank you so much
great video
ThAnk you…..life saver pretty much
This guy taught me more in 5 minutes than my teacher did in 5 weeks
FACTS
much easier to understand than my teacher in school...
thx
hows life bru
This is very helpful i think
Thank you!
i have to take my alegbra 1 keystone exam in about 2 hours. NOT PREPARED AT ALL. Thank you!
Thank you so much! I can clearly and fully understand graphing inequalities. Best youtube Math channel.
NOPE, 10 YEARS AGO GEEZ.
What I'm so confused!
Thank you

now if x was 1 over 3 x that is a fraction and we start y 3 x 0 we would go y 4 x 3 then y 5 x 6 and so on for minus we would go down i hope this helps
THANK YOU
THANK YOU.
this is great, thanks, I found it just in time, right after my finals
its 12:39 :(
i found this helpful
thank youuu, my chances of failing my math test has decreased after watching..I hope. 😁
this didnt even help me one bit !.. it just confused me even more :(..... Thanks
Come and check out my videos. I guarantee that you will understand this topic the way I teach it. Subscribe if you do as well.
It's was really helpful :) thanks =D

sal i love u if i get into uni its thanks to u
*insert prodigy leveling up sound*
Thx for the second equation b/c I have really bad trouble on that one. Now I understand it more easier.

ARE YOU IN INDIA, IF YOU ARE THATS COOL.
helped a bit, but you were teaching things backwards!
this is great
1:22
Why do you go one in the x direction? Where did that one come from?
Is it because 4-3 is one?
I'm confused help :(
we go in the one direction because youre supposed to graph the point. After you graph a couple of points, you graph or connect them to make a line. Why are you supposed to graph a line? Because this is math class.

THE DOOOOO
6:12 shouldn't the line be dotted?
Finally.. math in plain English. Thank you.
thanks :)
Where did you get the one on the X line of the graph
You go to a CC?
people who don't understand sal just doesn't understand math
haha i really dont understand but i like aot :p

Why doesn't the downvote work?
Victor Zhang yeah i dont understand it i have a 51 percent in my class
isn't that the reason why we're watching this vid to begin with?? So that we'd understand :l
Nice
I love this voice
Insane! I am watching 2021 videos the same guy is doing the same stuff.
but wait! his sound have developed .
saved me!
What app does he use
hi classmates from nativity i dont understand this at all
I think I have it now! I was plotting correctly and using the dash and solid lines. But when it came to coloring it in on the computer it would not work. I think I was coloring the line too or not going above what was included. Still a little tricky.
I DONT UNDERSTAND
This video is good. I don't know why people are getting confused.
This is mostly going to be useful for engineers(at least I know it will)
YUP NOT FOR ME
YUP
Who is here from Algebra 1? 😂
Its an algebra 1 standard. Almost everyone is here because of algebra 1
Was not confused at all.
Great explanation !
Well Done :)
YOUR BEING SARCASTIC, RIGHT!

When an 8:00 video is better than my teacher attempting to teach us for multiple hour long classes
FACTS
what is that board app that you are using please answer because i am a teacher and i want to use that app please reply ASAP.
what if the equation is -y

Trying Wiki when do u use stippling instead of shading in the graph
*divide both sides
